DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference is made to FIGS. 1 to 10 which show preferred embodiments of the present invention.

In a first preferred embodiment of the present invention shown in FIGS. 1 and 4 to 7, a shelf 10 is mounted to an office partition 12 by a first pair of brackets 40 attached to the rear edge portion 18 of the shelf 10 and extending between two removable covers 14 of the office partition 12 for connection to an internal framework of the office partition 12. A pair of angled support members 16 extend diagonally from the front edge portion 44 of the shelf 10. A second pair of brackets 42 are attached to the upper end of the angled support members 16 and extend inwardly above the removable cover 14 for connection to an internal framework of the office partition 12.

The first and second pair of brackets 40 and 42 used for mounting the shelf 10 to the office partition 12 are shown in FIGS. 4 and 6. A first pair of brackets 40 is attached to the rear edge portion 18 of the shelf. A second pair of brackets 42 is attached to the angled support member 16. The partition 12 shown in FIG. 1 is of the type described in U.S. Pat. No. 5,406,760 to Edwards issued Apr. 18, 1995 with a vertical post 11 at each end spanned by pairs of horizontal beams 13 on each outer side of the post 11. Both the first and second pair of brackets 40 and 42 are adapted to clamp onto the horizontal beams 11 for mounting the shelf 10 to the office partition 12. Specifically, each bracket 40, 42 comprises an upper jaw 46 and a lower jaw 48. The upper jaw 46 and lower jaw 48 clamp onto the horizontal beams 13 of the internal framework of the office partition 12 such that the beams 13 are positioned in between the upper jaw 46 and the lower jaw 48. Thus, the shelf 10 is securely mounted to the office partition 12.

The shelf 10 has a front edge portion 44, a rear edge portion 18, and two side edge portions 50. The length of the shelf 10 between each of the edge portions 50 is not particularly limited. Similarly the width of the shelf 10 between the front edge portion 44 and the rear edge portion 18 is not particularly limited. The shelf divider system of the present invention can be designed to accommodate shelves of any length. The shelf 10 has a flat upper surface 52 and a flat lower surface 54.

The rear edge portion 18 includes an elongated slide member 20 which extends longitudinally along the rear edge portion 18. A divider member 22 is mounted to the slide member 20 and rests on the upper surface 52 of the shelf 10.

FIGS. 2 and 3 illustrate the divider member 22 in greater detail. The divider member 22 includes a divider panel 24, and a laterally projecting foot member 26. In the preferred embodiment, the divider member 22 is manufactured from a single metal sheet. The metal sheet is bent at a 90° angle about a fold line 25 to define the divider panel 24 and the laterally projecting foot member 26 on each side of the fold line with a bottom edge of the divider panel 24 joined to a side edge of the foot member 26. At the rear end of the foot member 26, the sheet is bent up at a 90° angle about a fold line 27 to form a back wall 56 with a rear edge of the foot member 26 joined to a lower edge of the back wall 56. When the divider member 22 is placed on the upper surface 52 of the shelf 10, as shown in FIG. 1, the foot member 26 rests flat on the upper surface 52 of the shelf 10 and supports the divider member 22 such that the divider panel 24 is disposed in an upright plane. Secured to the bottom of the front member 26 as by adhesive are two slider plates 80 each preferably of low friction plastic material which serve the purpose of assisting the front member 26 to the slid over the upper surface 52 of the shelf 10.

The back wall 56 and a finger carrying member 70 mounted to the back wall 56 together form a coupling member for coupling the divider member to the slide member. The finger carrying member is best seen in side view in FIG. 7 is an extruded member having a U-shaped clamp portion formed from a forward arm 71 and a rearward arm 72 joined by an upper bight 73 and adapted to fixedly receive the back wall 56 between its forward arm 71 and rear arm 72 as in a friction fit against removal. The rear arm 72 carries a finger member 28 which is joined at a front end to the rear arm 72 and extends upwardly and rearwardly therefrom to a distal end 75 forming a gap 58 rearward of the finger member 28 and forward of the rear arm 72.

The finger member 28 projects generally upwardly when the divider member 22 is placed on the upper surface 52 of the shelf 10 with the divider panel 24 disposed in an upright plane.

FIGS. 4 to 7 illustrate how the divider member 22 is securely mounted to the slide member 20. As best seen in FIGS. 5, the slide member 20 has a rear wall 60, a top wall 62 and a tab 32 of the slide member 20. The rear wall 60 is attached to and extends upwardly from the rear edge portion 18 of the shelf 10 above the upper surface 52. The slide member is bent at a 90° angle between the rear wall 60 and the top wall 62. The top wall 62 extends horizontally forwardly away from the rear edge portion 18 spaced above the upper surface 52 of the shelf 10. The slide member 20 is bent at a 90° angle between the top wall 62 and a front wall or tab 32 projects generally vertically downwardly to a lower distal end 33. An access opening 34 is provided between the lower distal end 33 of the tab 32 and the upper surface 52 of the shelf 10. The slide member 20 defines a longitudinally extending channel 30 therein. The channel 30 is formed inside the slide member 20 bounded by the upper surface 52, the rear wall 60, the top wall 62 and the tab 32. The access opening 34 of the channel 30 opens outwardly. The channel 30 faces away from the rear edge portion 18 out the opening 34 and inwardly across the upper surface 52 of the shelf 10. As seen in FIG. 6, inside the channel, inwardly from the access opening 34 the channel extends above the access opening upwardly past the distal end of the tab 32.

To mount the divider member 22 to the slide member 20, as shown in FIGS. 4 and 5, the divider member 22 is tilted and moved rearwardly such that the finger member 28 is inserted underneath the tab 32 through the opening 34 and into the channel 30 with the tab 32 to become received in the gap 58 between the finger member 28 and the back wall 56. To finish mounting the divider member 22 to the slide member 20, the divider member 22 is then pivoted clockwise as seen to the position shown in FIGS. 6 and 7.

As illustrated in FIGS. 6 and 7, the divider member 22 rests on the upper surface 52 of the shelf 10 with the foot member 26 on the upper surface 52. The finger member 28 on to the divider member 22 cooperates with the tab 32 of the slide member 20 to securely mount the divider member 22 to the slide member 20. The tab 32 is received preferably in a snug fit, into the gap 58 between the finger 28 and the back wall 56 of the divider member 22. In this configuration, the divider panel 24 is maintained normal to the rear edge portion 18 as well as generally vertical, and while securely mounted to the slide member 20, resists being moved from normal to the rear edge portion 18.

The finger carrying member 70 with the finger member 78 and it's associated gap 58 are shown to extend longitudinally on the back wall member that is with the finger member engaging the channel at longitudinally spaced locations along the channel to maintain the upright right plane of the divide panel at a relatively fixed angulation relative the channel and the upper surface. Providing increased length of longitudinal engagement between the tab 32 of the slide member 20 and the finger carrying member 70 is advantageous in maintaining the divider panel 24 to extend forwardly normal to the slide member 20 even if there may be a slip fit of the tab 32 within the gap 58. The interaction of the tab 32 and the finger member 28 and the gap 58 may be characterized as a removable clip structure. The divider member 22 may be located in any one of a plurality of different positions longitudinally along the slide member 20. The engagement of the finger carrying member 70 with the slide member 20 may preferably in the use position of FIGS. 6 and 7 permit the divide member 22 to be slid longitudinally relative the slide member 20 to any position along the slide member 20. Alternatively, when in the temporary raised position of FIGS. 6 and 7 the finger carrying member 70 and the slide member 20 may engaged so as to prevent longitudinal sliding and the divide member 22 must be tilted to assume the temporary raised position of FIGS. 4 and 5 in which the divider member 27 may side longitudinally relative the slide member 20 for repositioning.

The divider member 22 is present on the upper surface 52 of the shelf 10 and mounted to the slide member 20. The foot member 26 rests flat on the upper surface 52 of the shelf 10 such that the divider panel 24 is disposed in an upright plane. The divider member 22 is mounted to the slide member 20 such that the divider panel 24 extends forwardly over the upper surface 52 of the shelf 10 in a direction normal to the rear edge portion 18 of the shelf 10.

While mounted to the slide member 20, the longitudinal location of the divider member 22 can be manually adjusted by sliding the divider member 22 along the slide member 20. For example, the divider member 22 can be moved from the middle longitudinal location shown in FIG. 1 to a right hand longitudinal location simply by manually sliding the divider member 22 to the right.

Advantageously, the shelf divider system of the present invention allows for the divider member 22 to be slid to any desired longitudinal location along the upper surface 52 of the shelf 10. Further, the cooperation between the finger 28 member and the tab member 32 securely mount the divider member 22 to the slide member 20 such that the divider member 22 is not susceptible to being accidentally knocked off of the shelf 10. The finger member 28 and the tab 32 cooperate to also prevent the divider panel 24 from being moved from its position of extending in a direction normal to the rear edge portion 18 of the shelf 10.

If desired, even though the divider member 22 is securely mounted on the slide member 20, the divider member 20 can also be easily detached from the slide member 20. Beginning at the position shown in FIG. 6, the divider member 22 is manually pivoted to the position shown in FIG. 4, such that the finger member 18 can pass through the opening 34 underneath the tab 32 of the slide member 20, and the divider member 22 is thus removed from the channel 30.

The shelf divider system of the present invention allows for both easy mounting of the divider member 22 to the slide member 20 and easy detachment of the divider member 22 from the slide member 20.

An advantage of the first preferred embodiment of the present invention is that the slide member 20 serves as an effective rear stop mechanism at the rear edge portion 18 of the shelf 10. As seen in FIG. 1, the slide member 20 extends upwardly above the upper surface 52 of the shelf 10 along the rear of the shelf 10 presenting a forwardly directed stop surface. An article such as a book which may be placed on the upper surface 52 of shelf 10 and slide rearwardly will come to engage the tab 32 of the slide member 20 with the tab 32 acting as a forwardly directed surface of as a stop shoulder. This prevents articles on the upper surface 52 of the shelf 10 from contacting, for example, the surface of an office partition 12 to which the shelf 10 is mounted, as in FIG. 1, as can be advantageous to prevent books and the like on the shelf being pushed rearwardly into potentially damaging contact with the cover 14.

In the first preferred embodiment of the present invention, the slide member 20 is positioned at the rear edge portion 18 of the shelf 10. The slide member 20 when located is along the rear edge portion as contrasted with along the front edge portion of the shelf, has the advantage that the rear edge portion is less exposed and therefore, less likely to be damaged by physical contact as by dropping heavy books on the like on top of the slide member 20. Furthermore, the presence of articles such as books on the upper surface 52 of the shelf 10 provides additional protection to the slide member 20 on the rear edge portion from physical contact. A similar slide member 20 to that shown in FIGS. 1 to 7 could in another embodiment be placed along the forward edge portion 44.

Reference is made to FIGS. 10 and 11 illustrating another embodiment of the invention which is the same as the embodiment shown in FIGS. 5 and 7 however in which the back plate member 26 includes inner leg portion 90, a horizontal flange 91 which extends rearwardly to a downwardly extending rear tab 93. The back plate member 26 with inner leg portion 90, its top flange 91 and rear tab 92 serve as a coupling member or finger member which is received in the channel 30 by tilting the divide member 22 from the temporary raised portion of FIG. 10 to the rear position of FIG. 11. The rear tab 92 may preferably flare rearwardly at its lower end such that the width between the front surface of the inner leg portion 90 and the rear surface of the rear tab 92 will exceed the width of the channel 30 between the tab 32 and the rear wall 60 to provide a friction fit against longitudinally sliding in the use position. As seen in FIGS. 10 and 11 the back plate member 26 provides finger member in the form of an outwardly and downwardly open hook member with the back plate member 26 forming an inner leg portion 90 merging with the top flange 90 as a bight portion from which an outer leg, the rear tab 92, extends downwardly.

FIG. 12 illustrates another embodiment of the invention in a view the same as FIG. 11 in which the back plate member 26 is bent to form an inwardly and downwardly open hook member with the back plate member 26 having an outer leg portion 94 with a bight portion 94 extending inwardly to an inner leg portion 96. In FIG. 12 the guide member 20 may also be characterised as a hook member with an outer support leg portion, the rear wall 60; a bight portion, the top wall 62, and an inner leg, the tab 32, with the access opening 34 between the inner leg and the upper surface 52. Further modification of the guide member 20 and the finger member may be provided, as for example with the embodiment of FIG. 12 modified to eliminate the bight portion 95 and the inner leg portion 96 and the channel 30 merely having a width between the tab 32 and the rear wall 60 equal to the width of the outer leg portion 94.

FIG. 8 illustrates a second preferred embodiment of the shelf divider system of the present invention. The embodiment of FIG. 8 has a construction of the slide member 20 and the divide member 22 identical to that in the first embodiment of FIGS. 1 to 7. As illustrated in FIG. 8, two or more divider members 22 can be mounted to the same slide member 20, thus dividing the shelf 10 into three or more separate sections. In FIG. 8, the two divider members 22 have been positioned one at a left hand longitudinal location and the other at a middle longitudinal location. FIG. 8 differs from FIG. 1 in that brackets 64 are attached to the two side edge portions 50 of the shelf 10. Each side bracket 64 has a back edge 66 from which a pair of tabs 68 extend. These tabs 68 are adapted to be engaged into corresponding slots 67 provided in the posts 11 on each end of the office partition laterally of the cover panels 14 as seen in FIG. 2 to which the shelf 10 may be mounted. Such tab and slot arrangements are well known and slot carrying channels may for example be mounted to building walls, in cabinets, or other furniture items.

Whereas the first embodiment of FIGS. 1 to 7 is adapted for off-modular connection between posts 11 of the partition, the embodiment of FIGS. 8 is for modular connection spanning longitudinally between the posts 11.

Reference is made to FIG. 9 which schematically shows a pictoral view of a storage cabinet 80 having two forward open horizontal upper shelves 81 and 82 and a filing drawer 83 therebelow adopted to be slid horizontally between an extended position as shown and a retracted storage position not shown within the confines of the cabinet 80. Four divider members 22 in accordance with the invention are schematically illustrated as coupled to the cabinet 80 via four corresponding guide member 20. On the top shelve 81 a first guide member 20 extends along one side edge of the shelf 81 with its divide member 22 to the slideable forwardly and rearwardly. Another guide member 20 extends along a rear edge of the shelf 85 with its divider member 22 to be slidable laterally side to side. The drawer 83 has a bottom support surface 85 with one guide member 20 extending along a side edge of the bottom surface 85 and its divider member 22 slidable forwardly and rearwardly and another guide member 20 extending along a forward edge of the bottom surface 85 with its divider member 22 slidable laterally side to side.

The finger member 28 may have many different forms than that shown in the various embodiments. It may be attached to the divider member 22 by various methods including welding, an adhesive, screws or the like. In the preferred embodiment shown in FIG. 2, the finger 28 is attached to the back wall 56 of the divider panel 22.
